About Us


Severn Biotech is an independent British manufacturer founded in October 1989 by Andrew Smart, BSc (Hons) MSc, M.IoD.

Severn Biotech Ltd started by making oligo-nucleotide probes and primers for PCR and gene sequencing, supplying workers in the field of chromosome walking and genetic testing

The company quickly diversified and created a laboratory reagents division specialising in the manufacture of liquid acrylamides buffers and electrophoresis materials used in Molecular Biology laboratories.

In 1993 Severn Biotech moved into to Peptide Chemistry as the demand for custom peptide molecules started to grow .This became more mainstream as the need to create polyclonal antibodies and epitope mapping increased.

Severn Biotech has continued to “organically” grow over the last 33 years and now manufactures a wealth of different laboratory materials.

The present catalogue now lists over 400 chemical products which are highlighted in different categories.
